mysql 批量修改表列明为大小写

根据表名 修改为小写

SELECT
concat( 'alter table ', TABLE_NAME, ' change column ', COLUMN_NAME, ' ', LOWER( COLUMN_NAME ), ' ', COLUMN_TYPE, ' comment '', COLUMN_COMMENT, '';' ) AS '修改脚本'
FROM
information_schema.COLUMNS
WHERE
TABLE_NAME = '表名';

根据库名 修改为小写

SELECT
concat( 'alter table ', TABLE_NAME, ' change column ', COLUMN_NAME, ' ', LOWER( COLUMN_NAME ), ' ', COLUMN_TYPE, ' comment '', COLUMN_COMMENT, '';' ) AS '修改脚本'
FROM
information_schema.COLUMNS

WHERE
TABLE_SCHEMA = '数据库名'

 大写的话 把  LOWER 改成 UCASE
